What Does AP-233 Cover?

• Requirements: text and model-based + requirements traceability

• System and Subsystem views including hierarchies (BOM, CFI, FD, HW, SW)

• System Behaviour and Functional Architecture– functional decomposition, interfaces, &

allocation– functional & data flows; behaviour models;

finite state machines, etc.

[ISO STEP, INCOSE TIWG ]

10

What Does AP-233 Cover?

• System Physical Architecture and Interface Control– component decomposition, interfaces, &

allocation– parts libraries & product lines

• System Properties, Classification and Data definition

• System Engineering and Program Management • Model layout and presentation information

AP233 Data Exchange Demonstration

• Go To http:\\ap233.eurostep.com for info and the Ap233 Demonstrator you can download for your use.

• Version 1.5 is based on an extended AP233 PBR model (alpha 1b).

• This extended model includes the schema module from PLCS which has been used in the demonstrator to display project plans and activity models.

• A Microsoft Project (TM) to AP233 converter also installs with version 1.5
